At times we approached near enough to the fields to see how they were laid out. From the gates long canals, six to eight feet wide, led back sometimes eighty or a hundred rods. Across these and at right angles, head channels were cut and between them the fields were plowed in long straight lands some two rods wide, separated by water furrows. Many of the fields were bearing sugar cane standing eight feet high. The Chinese do no sugar refining but boil the sap until it will solidify, when it is run into cakes resembling chocolate or our brown maple sugar. Immense quantities of sugar cane, too, are exported to the northern provinces, in bundles wrapped with matting or other cover, for the retail markets where it is sold, the canes being cut in short sections and sometimes peeled, to be eaten from the hands as a confection.
Much of the way this water-course was too broad to permit detailed study of field conditions and crops, even with a glass. In such sections the recent dikes often have the appearance of being built from limestone blocks but a closer view showed them constructed from blocks of the river silt cut and laid in walls with slightly sloping faces. In time however the blocks weather and the dikes become rounded earthen walls.
We passed two men in a boat, in charge of a huge flock of some hundreds of yellow ducklings. Anchored to the bank was a large houseboat provided with an all-around, over-hanging rim and on board was a stack of rice straw and other things which constituted the floating home of the ducks. Both ducks and geese are reared in this manner in large numbers by the river population. When it is desired to move to another feeding ground a gang plank is put ashore and the flock come on board to remain for the night or to be landed at another place.
About five hours journey westward in this delta plain, where the fields lie six to ten feet above the present water stage, we reached the mulberry district. Here the plants are cultivated in rows about four feet apart, having the habit of small shrubs rather than of trees, and so much re-
